New Technologies, Old Technologies and Libraries: the Juggling Act

Sue Steele & Hans Groenewegen, Monash University Library

Abstract

Libraries have a heavy investment in information technology and are generally quick to take advantage of innovations. They also have huge capital investments in paper-based technology and tools for access which they wish to maximise within the new IT-based scenarios. The number and range of technological options available at any time is increasing rapidly and it is not always possible or practical to adopt every one. Libraries need to evaluate both old and new systems and evolve a mix which best serves their needs and those of their clients.

This paper will examine issues affecting the adoption of new technology and draw on examples of solutions devised within Monash University Libraries to take advantage of appropriate new technology while maximising existing services where these are still required .

Introduction

Almost every day there is a new technological development which might prove useful in a library. No library can adopt them all, and I doubt many would want to.

All innovations, technological or otherwise, have some things in common though. They involve time (and time is money even if the innovation comes free of charge but usually it doesn't), effort and cause change. Initially there is a need for evaluation of the product or service. No library can afford to thoroughly evaluate every innovation. Nor can it afford to completely ignore most of them. Just as libraries use tools to assist in material selection, so we need tools to assist with the selection and evaluation of technology.

Technological change has always been with us. It's simply more obvious when the changes appear to move towards digitising entire libraries and/or utilising networks to make materials available to users, both local and remote. Users themselves expect more from our services. They want access to information wherever they are. No longer is it acceptable to have to visit a library, or to wait several weeks for a document to be delivered. Increasingly users expect to get what they need at the touch of a button, or the click of a mouse. Often their expectations have been raised by publicity or promotion of a product which is still in a pilot stage, and therefore cannot be met or may not be able to be met immediately.

Meanwhile libraries and library staff are grappling with shrinking budgets, ever-growing collections housed in non-expandable space, with the need to do more with less that we all seem to face. Going digital may seem an attractive solution to some of these problems. It requires hard decision-making to replace some paper-based services with digital solutions instead of using them as a supplement, which has previously been more common. Library users and staff, in many cases, do not wish to forego traditional modes of service-delivery they have grown used to, even if they embrace some newer technological alternatives. Others may wish to embrace every new service as it emerges and cannot understand the relatively slow pace of change they perceive around them. This dichotomy makes the task of integrating technologies in the library more difficult.

Reasons for selecting a technological solution

At Monash we have found there can be many good reasons to provide technological solutions to problems. Specifically:
Offers new, improved or additional service
Paper-based technology is effectively one-dimensional. Access points and methods are fixed. Digitised services are multi-dimensional. They may provide keyword indexes to non-digital resources, or they may go one step further and store, index and deliver the full text, images, sounds or whatever makes up the information source.

Until quite recently, say the last 3 years or so, most of the digitised services we added to our libraries complemented existing services and provided better access to our own collections. They also increased users' awareness of the limitations of our collections, hastening the adoption of yet more high-tech solutions to document access and delivery. Examples of this type of technology include the online catalogues and the numerous CDROM databases acquired at Monash. Services such as Business Periodicals On Disc go one step further, providing a full-text product.

Our hopes and aspirations have generally been way ahead of what the available technology could deliver. Recently technology has narrowed the gap considerably. Relatively fast, cheap and reliable networked services combined with more attractive user interfaces changed the way many people view information storage, retrieval and delivery. We can satisfy increasing numbers of user requests via rapid electronic delivery. We can elect to store some information electronically on-site, and/or to access local or overseas databases and document delivery services for others. CARL UnCover and Nexis provide this kind of service. Nexis has proved so popular at Monash that we have dedicated terminals in many branches.

Provides service to local and remote users
Before the advent of networked and other digital products, most of our users had to visit the library to use our services. There was Inter Library Loan, of course, and some other at-a-distance services, but these were mostly specialised and not widely available. Distance education is probably an exception, but even there, many services were provided in the library by library staff, and results mailed to users, for example catalogue searches or database searches.

Providing remote and local access to a service helps maximise its use. It can be available 24 hours a day to users with appropriate hardware and software. It also reduces some of the pressure on the library's staff and facilities.

In many institutions extra-mural access can be broken into two parts: access within the institution and access from outside the institution (modem or Internet). In an ideal world a single service would rill all users' requirements. In practice it is not so easy. Some types of services can be quite readily provided throughout the institution, but not so easily to the outside and it may be that the needs of each group differs. This leads to some interesting issues of choice or duplication of services.

Our method of CD-ROM database delivery reflects this. At most Monash campuses, there are CDs networked via Novell file servers - providing good access to library user, offices and laboratories, and rather poor access to modem users (if at all). At the Gippsland campus, however, similar services are provided via Gilbert (an OVID based solution running on a Unix server) which provides in-library, on-campus and modem access. Gippsland serves thousands of off-campus users, so this is the best solution for them.

Allows multiple-user access to a single service
Unless we have multiple copies of most non-digital products, we can only allow one user access at any given time. This limitation is generally lifted when an online solution is selected. Of course the price paid for this is sometimes quite high - and we purchase limited user licenses for some products based on a best-fit which balances what we think we need with what we can afford.

At Monash, for example, we regularly have well over 220 connections to the library system for most of the working day, and a similar number of connections to the world wide web through our proxy server. The physical limits to the numbers of connections in these cases are quite high for example 400 in the case of the library system and, if they are reached, can be increased by the purchase of more hardware. This is a large investment but the cost per connection per year (averaging costs over the life of the system) is not all that high. When we look at networked CDs we can only allow/afford a small number of simultaneous users, less than 5% of those accessing the catalogue or WWW in most cases. Increasing the number of simultaneous users involves negotiating a new license arrangement with the vendor.

Provides improved access to existing services
Online catalogues are very good at this. Suddenly people begin using and borrowing all sorts of things they never knew existed until the catalogue was online, or in their office or home. Access to online databases can work in a similar way, especially if the search results can be somehow linked to the library's holdings, so that users can select from them before resorting to other institutions.

There are other ways to improve access/delivery of course. At Monash we have begun to use the interactive nature of world wide web an a number of ways. Our Document Delivery Unit has an online request form which simplifies record-keeping for library staff and allows users to fill in a form whenever and wherever they like. The Document Delivery Unit is also developing some in-house forms such as inter-campus delivery requests which will help speed up the service. We have a similar form for library users which is attached to wwwlib, the web-based front end to our library system. We also provide online reservation of library materials, and online renewals.

In conjunction with the Information Systems Centre we are developing an automated telephone-renewal service as part of a suite of library-based information available through a 1-900 number. Services such as Nexis and UnCover provide rapid document delivery, for a fee. We've provided services like these (but paper-based and mail-bound) for a long time, the change here is mostly to do with speed of delivery.

May help constrain physical growth
Libraries seem to be perpetually short of space, often chronically so. We weed, we place less-used items in compactus or off-site storage, but many of us still grow. Clearly replacing some paper- based products with online ones can save space. A few multi-purpose workstations take up less space than runs of books, journals, indexes and abstracts, and they can be anywhere, not just in the library. By adopting technology the library can share infrastructure whereas previously all (or most) of its infrastructure was library specific.

May provide cost savings
In some cases, a technological solution may save money. In others, it may be cost-neutral or actually cost more, but provide added benefits which make up for this - such as improved service. In addition to up-front savings, there may be other hidden savings such as initial processing, re-shelving, space.

Looking around, it is difficult to find services which have saved large amounts of money, although the cancellation of an expensive paper-based abstracting or indexing service in favour of commercial online access is one example. There are many examples of technological solutions providing additional benefits which more than outweigh any additional cost. Monash examples include Sesame2 (the integrated online system) which allows modes of access and service improvements in areas such as serials management and student reading which were not possible without the system.

Preservation and protection of materials
Digitising some rare or valuable items can help preserve and protect them from theft, vandalism, wear and tear. Many users' needs may be satisfied through the digital facsimiles rather than requiring the original item. Digital copies are easily reproduced, so the items can be sold or distributed widely if desired.

Options for introducing technological solutions

When a technological solution has been decided upon, there are a number of different options of implementing it. As outlined below.
Add a new service
This is probably done least when introducing a technological service or product. Usually a digital solution is adding to or replacing more traditional forms of service. Examples of new services include some of the information products and services available via the net (especially primary source materials and previously unpublished data), provision of networked workstations in libraries for Internet access, and services such as the ability to connect to remote hosts and databases from public access terminals.

At Monash, we have just begun providing networked workstations within libraries and hope to integrate them with other library services rather than adding another set of workstations for users to access. We are also providing remote access to other libraries from OPAC terminals (this service is not available to non-Monash users). On a smaller scale, each time we subscribe to an electronic journal or other service not previously available in non-digital format, we are adding a new service. We treat these additions in the same way as any other new subscription, and subject them to the same selection criteria.

Replace an existing service
This is the most common method, especially for very large or expensive solutions. Often with large projects, the intent is to replace an existing service with a better one. It's generally more cost-effective because we can offset the old expenditure against the new. It's also less labour-intensive, once the new service is fully operational and the old one has been phased out.

Integrated library systems fall into this category. Libraries will often replace the card catalogue with an online one without more than a passing thought (if all the records are in the online one), but agonise when an online service is added that duplicates a paper-based index or abstract. Why is this so one may ask. Monash is something of an exception here, with the Clayton branches hanging onto their card catalogues but that's because the quality of many online records is so poor. The card shelflist has closed.

Upgrade an existing service
This is an attractive solution in many ways. Upgrading is usually cheaper and less painful than replacement. Staff and users are already familiar with the existing system, so an upgrade should require less training and less PR work than a new system. Extending the life of an existing system gives a library some breathing space - especially if there isn't really anything better on the market at the time.

Upgrades fall into several categories. The most obvious involve purchasing more hardware or installing a new release of an existing system. Upgrading can also include things such as giving the system a face-lift - so that it appears different while still functioning the same way underneath. World-wide-web interfaces to library systems such as wwwlib fall into this category. This has given Monash library a chance to continue using what is an extremely powerful old-style library system with an attractive and intuitive user-interface.

Maintain old and new service
This is the most expensive and probably least-desirable option. It's most obvious when a paper-based and an online service are both provided, and where they are almost identical, or, more likely, where the online service does all that the paper-based one does, and more.

Less obvious, but becoming more common, is the use of two or more online products to provide the same service, perhaps to different groups of users. Sometimes this is unavoidable. For example, at Monash, at the time of writing, undergraduate students do not generally have access to off-campus telnet. This means we must provide all their bibliographic services in a format they can access on-campus. More particularly it means they cannot use any of the CAUL databases, even when these are relevant to undergraduates. Our solution is to provide networked CD-ROM databases as well as some online subscriptions. Thus, for some databases, Monash library is providing access to the same service in 3 different ways. It's necessary because it's the only way we can service all of our users at this time.

Methods for developing digital services

At Monash there are a number of methods by which technological services may be implemented:
Acquire an off-the-shelf solution
Many libraries have done rather a lot of this, and it makes good sense most of the time. Some systems, such as integrated library systems, are just too large and complex for an individual library to develop. Many products and services contain proprietary data and proprietary software such as search engines, and the only realistic approach is to purchase the ones your library requires. Even with non-commercial products, it's common sense to use one that exists rather than develop your own, unless your requirements are unique.

Libraries have traditionally used off the shelf solutions whenever they could. Many use a standard classification scheme, for example. Many catalogue on ABN. Relatively few use an in-house library system.

Develop a solution in-house
Sometimes no existing product or service can solve an information need. Then there are two choices: develop an information product or do without. A lot of libraries develop some information products in-house. Monash is no exception. We produce ALLI (Australian Legal Literature Index) for example. We have also developed an image-processing system for digitising, storing and retrieving exam papers and parts of this have recently been extended to our online Reserve Bookroom project.

Some locally-produced services can be sold to others, alleviating part of the development costs, or possibly making a profit. ALLI has always had a commercial aspect and is now available via KIWINET, LEXIS and Computer Law Services cd-roms.

Give an existing service a face-lift
This is an increasingly popular method of extending the life of a good product which was developed a while ago. Usually the underlying product remains unchanged, but a new user-friendly interface is applied. World wide web front ends to many databases and systems are one example of this, so are some z39.50 implementations. There's also a trend towards developing windows-based front ends to existing products, for example win-SPIRS and at Monash wwwlib the windows-PALS client.

This method protects our existing investment, which may be very substantial. It has the added advantage of providing several access methods to the same service in some cases. Obviously it will be cheaper to write a new front end than it will to develop a new system, or even to implement one in many cases. Tools for this type or work are now readily available, cheap, and often easy to use.

Take up underutilised features of existing services
Sometimes one of our existing systems can provide a solution to additional problems. There may be modules or features we have not previously explored because there was no perceived need, or because they were not well-developed initially but have improved with time.

There are several benefits to this approach. Staff and users are already familiar with an existing system, so an additional feature should be relatively easy to introduce. Initially, at least, there may be no need for a further outlay on hardware or software.

Bringing it all together

Clearly there is no right way to do things every time. Given a choice between an off-the-shelf solution that almost fits and one that would need to be developed in-house, the former is generally preferable. The best solution is one that will do what is required, and fit in with existing practices and products most easily. Unfortunately this is not always easy to achieve.

Monash, like many other libraries, has adopted a wide variety of technological solutions in the past. As far as practicable, the number of user interfaces and search engines has been kept to a minimum. Even so, a wide variety of interfaces had to be used to fulfill the range of services required. More recent developments such as web browsers and z39.50 clients are allowing us to begin consolidating some of these interfaces. At the moment we are using WWW and wwwlib in particular as the nucleus of what will hopefully grow into a common user interface for many of Monash Library's information services.

With wwwlib we are able to utilise the existing library database and search engine through a series of web cgi programs. We have also built on existing work with the imaging project to include scanned images of Reserve materials as URLs within the sesame database. These are converted to hot-links and users can display them within their web browser using a locally-developed tiff viewer. Through hot-links (any URL in a catalogue record is converted to a hot-link in wwwlib) we are able to provide direct links to any local or remote resources we deem of value to our users. We are also incorporating easier self-renewal of material on loan, and user-requesting of materials held at other campuses.

Using the web as the basis of a common user interface (or at least a common jumping off point) has a number of advantages for Monash. It is platform independent so we are catering to a wide range of users. A great deal of Windows-based software is freely available which fits in with the university's PC and Windows-based technology strategy. Web browsers such as Netscape facilitate access because our users are often familiar with the interface and because of the ease of adding on viewer applications. We have the flexibility to change the interface easily, and we are not creating additional searchable databases of materials held by Monash - the library system is still the main search tool, with the addition of a small amount of data to bibliographic, item or serial records. Links to other databases or search engines can be easily incorporated as and when required.

We are very pleased with the development so far and will explore ways of integrating other services and expanding the idea of a common user-interface. We will continue to use existing products and services and adopt off-the shelf-products for new or improved services where these fill our requirements. We will also develop new products when nothing suitable is available, endeavouring to build on existing systems and products at the same time.
